Router in bridge mode

I have a 2621 router leftin town A, settings as below. I have a 2621 router right in town B, settins as below. I cannot change the ip addresses or interfaces. To connect them I thought I could use a router in bridge mode and made a config 'middle' as below. It doesn't work. What is a good solution for this problem? Help.

Router left: int f0/0 description connected to bridge in the middle via x-cable ip addr 10.10.10.2 255.255.255.0 no shut int f0/1 description connected to NATO network ip addr 172.16.20.1 255.255.255.0 no shut

Router middle: int f0/0 description connected to router left via x-cable bridge-group 1 no shut int s0/0 description connected to router right via serial cable bridge-group 1 no shut

Router right: int f0/0 description connected to ICC network ip addr 172.16.10.1 255.255.255.0 no shut int s0/0 description connected to router middle via serial cable ip addr 10.10.10.1 255.255.255.252 clo rat 64000 no shut

Not sure about the entire setup, but I do note you have a /30 subnet mask on Right's s0/0 and a /24 on Left's f0/0.

Not sure about this one at all - if you don't run ip classless, I'm not certain your two 172.16.0.0 networks can see each other, unless you're using a static route on each end.

Good luck.

The /24 is a typo, should be /30 om both sides. I added 'no ip routing' in the midde and default routes on left and right. It works with ethernet on both WAN-links but 'middle'doesn't work as an encapsulation bridge from ethernet to serial end vice versa. So I need a soltion. Hans
